Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a three-stage slow-release blended fertilizer for slope protection plants and its preparation method, which can solve the problem that the nutrient ratio of existing fertilizers is relatively fixed, the utilization efficiency of fertilizers is generally low, and the improvement effect on soil is weak and cannot be used. Meet the lack of nutritional needs of plants at different growth stages, better ensure that plants get the necessary fertilizer nutrients throughout the growth cycle, promote the healthy growth of slope protection plants at all stages of growth, improve soil properties, and increase fertilizer use efficiency

Abstract

The invention provides a three-stage controlled-release bulk blend fertilizer for slope protection plants. The three-stage controlled-release bulk blend fertilizer is characterized in that the fertilizer is prepared by mixing an early-stage fertilizer, a middle-stage fertilizer and a later-stage fertilizer, wherein the early-stage fertilizer is a particle composed of an early-stage fertilizer inorganic fertilizer core and an early-stage fertilizer hydrogel layer coating the early-stage fertilizer inorganic fertilizer core, the middle-stage fertilizer is a particle composed of a middle-stage fertilizer inorganic fertilizer core, and a middle-stage fertilizer chicken manure organic fertilizer layer and a middle-stage fertilizer hydrogel layer successively coating the middle-stage fertilizer inorganic fertilizer core from interior to exterior, and the later-stage fertilizer is a particle composed of a later-stage fertilizer inorganic fertilizer core, and a later-stage fertilizer chicken manure organic fertilizer layer, a later-stage fertilizer diatomite layer and a later-stage fertilizer hydrogel layer successively coating the later-stage fertilizer inorganic fertilizer core from interior to exterior. The three-stage controlled-release bulk blend fertilizer for the slope protection plants and the preparation method thereof in the invention can better guarantee that the plants obtain necessary fertilizer nutrients in the whole course of a growth period, promote healthy growth of the slope protection plants in each growth stage and improve the utilization efficiency of fertilizer.

Description

technical field [0001] The invention relates to the technical field of inorganic-organic compound fertilizers, in particular to a three-stage slow-release compound fertilizer for slope protection plants and a preparation method thereof. Background technique [0002] In the production of modern agriculture, forestry, animal husbandry and other related fields, many new fertilizers have appeared, including compound fertilizers, organic fertilizers, biological fertilizers, organic-inorganic compound fertilizers, bio-organic fertilizers, organic-inorganic biological fertilizers, slow-release fertilizers, Controlled-release fertilizers, these fertilizers have their own characteristics. Compound fertilizer has the advantages of high nutrient content, less auxiliary components, high fertilizer utilization rate, convenient storage and application, etc., and plays an important role in promoting better and faster growth of plants. [0003] The three-stage slow-release blend fertilizer...
